ADUs Decisions in Allentown

An Accessory Dwelling Unit (ADU) is a secondary housing unit located on the same parcel as a primary single-family residence. ADUs go by many names - granny flats, in-law suites, backyard cottages, garage apartments, or casitas - but they all share the common characteristic of being smaller, subordinate residential units that share a lot with the main house.

Allentown's zoning is governed by a new Zoning Ordinance (Ordinance No. 16166), which City Council adopted on October 15, 2025 as part of the ZONE Allentown project. It took effect on January 1, 2026, replacing the prior 2015 ordinance, and was adopted alongside a new Zoning Map and updated Subdivision and Land Development Ordinance (SALDO, Ordinance No. 16167). The rewrite uses a form-based code approach that regulates the physical form and character of development, aiming to streamline procedures and encourage walkable, mixed-use patterns.

The ZONE Allentown ordinance organizes the city into several families of base zones. Mixed-use zones include the Storefront Mix zones (MX-D Downtown Core, MX-C Corridors, MX-S Suburban Centers, MX-N Neighborhood Centers) and the Residential-Office Mix zones (GX-D, GX-C, GX-N). Neighborhood zones range from NX and N1 (Urban Neighborhood) through N2 (Town Neighborhood), N3, N4, and N5. The ordinance also establishes Industrial zones and Public-Institutional zones (including Open Space). Each zone sets which building types and uses are permitted.

The city recommends two steps. First, use the interactive online Zoning Map (an ArcGIS platform) to search by address and click the parcel to see its zoning district and whether it falls in a historic district or overlay. Second, consult the Zoning Ordinance's Use Table to see which activities are permitted in that district. The full ordinance is posted online, and physical copies of the ordinance or map can be purchased at the Zoning office at City Hall, 435 Hamilton Street, 4th Floor.

Yes. Under the zoning ordinance, a zoning permit is required from the Zoning Officer before commencing a new or expanded use of land or a structure, constructing or placing a structure, installing signs, or creating additional dwelling units through interior alterations. The Zoning Officer reviews the application and may issue the permit only if the proposal complies with the ordinance. Zoning permit applications are handled by the Bureau of Planning and Zoning at City Hall, 435 Hamilton Street, 4th Floor.

The Zoning Hearing Board is a three-member board (with alternate members appointed as needed) established under the zoning ordinance. It holds public hearings and decides appeals of the Zoning Officer's decisions and determinations, applications for variances, and applications for special exceptions. The city provides an appeal application form, an appeal checklist, and a 60-day decision waiver form, and posts the board's meetings and agendas through its Legistar portal.
